Application filed Jul} 24,

To all whom/it may concern:

Be it known that I, F REbERIoK C. OVER- BURY, a citizen of the United States, residing at Hillsdale, in the countyof Bergen and State of New Jersey, have invented new and useful Improvements in Ornamental Roofing, of which the following is a specification.

The object of the present invention is to produce an ornamental roofing material, either in the form of sheets or of strips or slabs, in which each element has its surface lined or striped.

It is customary, in the manufacture of roofing, to. coat the felt (which has been saturated or impregated with asphalt or equivalent water-repellent compound) with a relatively high-melting-point asphalt, and, while the coating is plastic and adhesive, to partially embed therein crushed flaky slate of any suitable color; and it has been pro posed to employ slate or grit of different colors, and tosupply the same in parallel bands or stripes of contrasting colors.

In the present case, I propose to coat the sheet as usual and to applya layer of crushed slate or grit to the coating, much as ordinarily, but to remove .a portion of the coating so as to leave zones or bands which are 'unco'ated and unsurfaced with the slate-0r grit, and then to apply a colored plastic water-repellent material to such uncoated zones, with the result that the surface of the sheet has bands or zones of slate, and interbands or zones of the colored waterrepellent material. The sheet thus formed may be wound into a roll for shipment, so as to be subsequently laid flat on a roof, or it'maybe divided transversely into shingle strips or'slabs. In the latter case, the strips 40 or slabs are laid in overlapping rows and simulate shingles or tiles.

' On the accompanying drawing,

Figure 1 represents more or less conventionally and diagrammatically an apparatus for carrying out the process.

Figure 2 represents the comb for stripping the coating from the parallel zones of the sheet.

Figure 3 represents the rolls for applying the colored plastic coating to the uncoated zones.

Figure 4 represents the finished sheet.

Referring to said drawings, the roll of dry felt is shown at 10, and the sheet is 1920. Serial No. 398.681.

tank 11, which contains molten asphalt or its equivalent, and thence through squeeze rolls 12 to remove the surplus saturating compound. The sheet then passes under roll 13, over rolls 14 and 15 (the latter being termed by. me the-bed roll), then aroundv roll 16, and around roll 17 whence it passes to the set of cooling or refrigerating rolls indicated as a whole at 1'8. As the sheet travels in its tortuous path from roll 13 to the cooling rolls, it is treated as will now be described. At 19 there is a smooth cylindrical coating roll which dips into a pan or v trough 20, to which molten asphalt is de-' livered by a spout 21 from a reservoir tank 22. A distributing roll 23 is located between rolls '19 and 14:, and receiving the asphalt from the former applies it to and spreads it on the face of the sheetfrom edge to edge thereof. The asphalt is soft and plastic, and now, by means of a comb 24;, set above the bed roll 15, I. plow or wipe off the asphalt fromparallel zones, thus leaving the sheet withuncoatedstripes to which slatelor grit will not adhere to an appreciable extent. The sheet, with-its parallel bands of adhesive coating, is now passed under a shower of crushed slate, grit or other crushed mineral material of the desired colorsay, blueblack, green, red, brown or the like. This material is contained in a hopper 25 and is delivered thereto from a source of supply indicated at 26 through a conduit 27. In passing around the roll 16, the slate is embedded. in the stripes of adhesive coating, the surplus being returned to'the hopper 25, which is made flaring for this purpose. I now apply stripes of adhesive water-repellent material to the uncoated zones of the sheet, so as to fill the grooves formed therein by the comb and the application of slate to red or brown color. However, the coating.

may be of any color such as may be desired, so that a contrast will be made with the color of the crushed slate or other mineral which is partially embedded in the previously coated zones, This second adhesive has circumferential flanges equal in width.

to the uncoated zones on the sheet, so that the plastic compound carried up on the surface of the roll 31 will be transferred to the said previously uncoated zones, as the sheet passes around roll 17. The transfer roll is shown at 32, and its'circumferential ribs orflanges are indicated at 33, see Figure 3,

It will be understood, ofcourse, that the coating compounds in tanks 22 and 28 are kept in a 'hot molten state by any usual or suitable means, and that suitable powertransmittingdevices are employed to effect the rotation of thevarious rolls, where such power rotation is desirable.

After being treated as hereinbefore described, and after passing through the cooling rolls 18, the sheet may be passed through a festo'oning mechanism, indicated conventionally at 34:, and then delivered to ca machine 35, severed into slabs or strips.

In Figure 2, the operation of the comb is by which the sheet is chopped or In Figure 4:, the finished sheet is shown tconventionally'. It has the mineral- 'or slate-surfaced parallel zones (Z, and the intervening zones 6 which are surfaced with the colored coating.v When the sheet is severed on the transverse lines az-m, shingle strips or slabs are formed which may be laid to produce the effect of shingles, or other individual elements.

What I claim is z- A roofing material comprising a fibrous waterproof foundation, having on its face spaced parallel zones of asphalt, surfaced with crushed mineral, and intervening zones of a plastic colored waterproof -compound, which contrasts in color with the mineralsurfaced zones.

In testimony whereof I have affixed my signature.
